This invention relates to anfimproved gaging device,- and has forjitsY primary object, to provide such adevice Whereb-yprevious to assemblythe seating portions on the front and rear inner hubs for 'motor lvehicle Wheels can be quickly gaged Within the-most' practicable'degree of accuracy.

' Further' objects, and 'objects relating*v to economies of production and details of construction, Will definitely.' appear from the detailed description to follow.' I accomplish the objects of my invention bythe devices and means described in the followingf'specifi'cation. My invention is clearly pointed out in the appended claims'. AAstructu're constituting a preferred embodiment of my invention is illustrated' in the accompanying drawings, forming a part of this specification, in which:y Figure I isa top plan view of my gaging device, showing a front innerv hub in gaging position.

The Ienlarged-portion 15 ig.I -I) on the spindle 12 is adapted to lit snuglyy 1n the bearing surface 19 and the annularshoulder 21 rests on the upper end ofthe enlarged portion l'vvhereby the hub 1,8 isseate'd on the spindle 12. vThe hub 18 has an enlarged pyramidal portion v22 wh1ch`, in--the illustrative form of embodi-V ment, 1s a V-decagonal -pyramid having like faces 24. It is obvious, ofcourse, that the portion 22 may have any desired. number of faces or sides. The Wheelhub (not shown) has a ortionv complemental to the portion 22 oft efinner hub; The faces of portionf 22 of the inner hub are machined to secure a proper 'seating surfacex For seating an inner rear hub v29 1n' position to b e-gaged, I provide the sleeve (Fig. iv) i 24S- having the circularhorizontal flange 26l which proj ectsdownvvardly at its outer edge whereby the sleeve25- isvseated on the base 10.:"Anenlarged circular flange 27 Vonjthe inner end of the hub rests onthe flange 26 yvlienV in position tov be gaged. *A center- Ing ring`28' is mounted about the upper portionofthe sleeve25and Vis'adapted for engaging the innerfside of a circular Harige l 42'Within the enlarged portion 30 of 4the rear inner hub and centering thesaine about the upper portion ofthe sleeve 25. The

A' Ushaped member "30 is provided at its f terminals 'with inwardly projecting portions orfblocks 31.L rlfhese blocks have diametricallyopposedfaces-32, complemental to the diametrically opposite faces of the 'decago-` Vnally 'sidedjportions 122 and 30V of thev respective frontvinner, hub 18 and the rear inner hub,29f -Aiiat surface 33-is provided lonf-the' external' side. ofthe portion -intermediatethe'termina-'ls of the U-shaped member y30.i Centrally ofthe flat surface vis'p'ro'- vided an opening 234 having the annular Y offset'or seat :35, near'itsfinnerend. A -bushjing ihasalange l37 and adjacent this i nange, .a gropvees'iene-bushing being adaptof the spindle 12 has the one-half surface 39 offset and lower than the other one-half. surface 40. This offset may be lany desired fraction of an inch, depending upon the approximate degree of accuracy with which it is desired to gage the! hubs.

c In the operation of the above described device, the inner front hub 18 is first mounted for gaging (Fig. II), or if it is desired to f gage the rear inner hub 29, the hub would be mounted as illustrated in Fig.' IV. The U- shaped member is then positionedv on the upper end of the spindle 12, (Figs. II and IV) and if the faces 32 of the lblocks 31 slide down diametrically opposed sides24 ofthe front inner hub 18 orthe rear inner hub 29jto such an extent that either the offset surface 39 or the raised surface 4() on the end of spindle 12 is approximately flush ii with the surrounding surface of thel bushing 36, the diametrically opposed'sides 24 of the hubs are properly machined .for seating v the outer hub. Agaimvthe raised surface 40 may be slightly abovethe surroundingsurface of the bushing 36 and the offset surface 39 slightly below, and yet the sides 24 maf shined within the'proper degree. In other words, the two ksurfaces provide plus and minus limits within which the sides 24 of the' hubs are gaged. The relation of the surfaces 39 and 40 to the'adjacent surface of the bushing 36 can be found by. the oper# ator sliding a finger over the adjoining surfaces and it has been Vfound in actual practice that a high degree of accuracy can thus be obtained.

AI have herein described, and illustrated in the accompanying drawings, the use of my invention n gaging the wheel seat on a front and rear inner hub. The hub of a certain form, and it is to be understood that my invent-ion is not to be so limited. The invention is susceptible of considerable vam riation lwithout 'departing from thespirit g thereof, and, therefore, I desireto claim my y invention broadly, as well as specifically,- as
